[0028] As Figures 1 to 7 shown, a nano fiber production and collection device includes a production and collection device main body 1. Two first side plates 2 arranged symmetrically are installed on the upper side of the production and collection device main body 1. Installation concave seats 6 are fixedly connected to the upper sides of the two first side plates 2. Bearings 7 are installed inside the two installation concave seats 6. A pneumatic shaft 8 is fixedly installed together inside the two bearings 7. A nano fiber main body 11 is sleeved on the outer surface of the pneumatic shaft 8. Through the setting of the pneumatic shaft 8, the pneumatic shaft 8 can be inflated, so that the surface of the pneumatic shaft 8 can protrude, which is used to fix the reel for collecting nano fibers and is convenient for taking out the nano fibers on the reel.

[0029] U-shaped top seats 9 are clamped on the upper sides of the two first side plates 2. Two elastic snap plates 10 for fixing the U-shaped top seats 9 are connected to the bottoms inside the two first side plates 2. Through the setting of the elastic snap plates 10, as long as the elastic snap plates 10 are outwardly buckled, the fixation of the U-shaped top seats 9 can be released. Two limit insertion rods 12 are slidably clamped on one side of each of the two first side plates 2. A driven gear 15 is fixedly connected to the outer surface of the pneumatic shaft 8. A gear rotating shaft 13 is rotatably connected to one side of the first side plate 2. The driven gear 15 meshes with the gear rotating shaft 13.

[0030] Two second side plates 3 and a third side plate 4 arranged symmetrically are fixedly installed on the upper side of the production and collection device main body 1. The third side plate 4 is located between the first side plate 2 and the second side plate 3. Rotating rollers 5 are rotatably connected to the inner sides of the two second side plates 3. Rotating rollers 5 are rotatably connected to the inner side of the third side plate 4. Through the setting of the rotating rollers 5, the one-high-one-low rotating rollers 5 can assist in collecting nano fibers, enabling the collection work to be carried out stably and efficiently and being convenient to use.

[0031] The inner sides of two third side plates 4 are rotatably connected with a double-headed threaded rotating rod 16. Symmetrically arranged two threaded connecting plates 18 are threadedly connected to the outer surface of the double-headed threaded rotating rod 16. The left sides of the two threaded connecting plates 18 are fixedly connected with first bent plates 19. Telescopic plates 20 are slidably connected to the inner sides of the two first bent plates 19. Cam movable rods 22 distributed in an array are rotatably connected to the inner sides of the two telescopic plates 20. One side of the telescopic plate 20 penetrates through the first bent plate 19 and extends to one side of the first bent plate 19. First springs 21 are connected in an array between the two telescopic plates 20 and the first bent plates 19.

[0032] The right sides of the two threaded connecting plates 18 are fixedly installed with second bent plates 24. Second springs 25 are connected in an array to the inner sides of the two second bent plates 24. Baffles 26 are installed on the inner sides of the two second springs 25. Through the installation and use of the cam movable rods 22 and the baffles 26, the two can adaptively adjust and move to adapt to limiting nanofibers of different sizes, facilitating the smooth collection of nanofibers. The front side of the double-headed threaded rotating rod 16 penetrates through the third side plate 4 and extends to the front side of the third side plate 4. The front side of the double-headed threaded rotating rod 16 is fixedly connected with a second servo motor 17 through a motor mounting plate. Two limiting cross bars 23 arranged in parallel are connected to the inner sides of the two third side plates 4. The two limiting cross bars 23 are slidably connected to the threaded connecting plates 18. Through the arrangement of the limiting cross bars 23, the movement trajectories of the two threaded connecting plates 18 can be restricted by the two limiting cross bars 23, enabling the two threaded connecting plates 18 to move back and forth smoothly for adjustment, which is convenient to use.

[0033] The inner side of the limiting insertion rod 12 penetrates through the first side plate 2 and extends to the inside of the U-shaped top seat 9. One side of the gear rotating shaft 13 penetrates through the first side plate 2 and extends to the other side of the first side plate 2. The rear side of the gear rotating shaft 13 is fixedly connected with a first servo motor 14 through a motor mounting plate.

[0034] Positioning grooves 111 are opened at both ends of the two U-shaped top seats 9. The positioning grooves 111 are adapted to the elastic snap plates 10. The inner sides of the elastic snap plates 10 are snap-connected to both ends of the U-shaped top seats 9 through the positioning grooves 111.

[0035] The working principle of a nanofiber production and collection device provided by the present utility model is as follows:

[0036] By respectively placing the two bearings 7 on the air shaft 8 into the two mounting recesses 6, and then successively clamping the two U-shaped top seats 9 above the two first side plates 2. At this time, the four elastic snap plates 10 can be inserted into the positioning grooves 111 of the two U-shaped top seats 9 to limit and fix the two U-shaped top seats 9. Then, the limit insertion rods 12 are successively clamped to one side of the two first side plates 2, so that the limit insertion rods 12 can reinforce the installation of the U-shaped top seats 9. In this way, the two U-shaped top seats 9 can be easily installed or disassembled by means of clamping, and the U-shaped top seats 9 can position the bearings 7 in the mounting recesses 6, so as to firmly fix the air shaft 8. At the same time, as long as the U-shaped top seats 9 are removed, the nanofibers on the air shaft 8 can be quickly removed. The operation is simple, time-saving and labor-saving, which is used to improve the production efficiency of the nanofiber production and collection device. Then, the installation of the air shaft 8 will also drive the driven gear 15 at the air shaft 8 to engage with the gear rotating shaft 13. Subsequently, the nanofiber body 11 is wound around the air shaft 8 along the two rotating rollers 5, and then the output shaft of the first servo motor 14 drives the gear rotating shaft 13 to rotate. In this way, the air shaft 8 at the driven gear 15 can slowly rotate to collect the nanofibers, ensuring the stable progress of nanofiber production and collection;

[0037] By driving the double-headed threaded rotating rod 16 to rotate through the output shaft of the second servo motor 17, the two threaded connecting plates 18 on the double-headed threaded rotating rod 16 can move towards each other. In this way, the telescopic plate 20 with the first spring 21 installed at the first bent plate 19 and the second bent plate 24 can move together and fit to both sides of the nanofiber body 11. Then, the two groups of concave wheel movable rods 22 with elasticity and the two baffles 26 with the second spring 25 installed can limit and guide the collected nanofibers, preventing the nanofibers from shifting during collection and affecting the quality of nanofiber production and collection.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
